I have two bedrooms over a one car garage. These two bedrooms are always noticeably warmer or cooler than the rest of the house so I would like to improve the insulation in the ceiling of the garage. The garage ceiling is open (no sheet rock no drop ceiling) so I have easy access. Currently there is fiberglass insulation in place. The kind made for walls with kraft paper on one side. The kraft paper is facing the floor of the garage. I am concerned about air infiltration. I have hardwood floors above which are installed over what looks like wood slats (not plywood). In any case there are lots of cracks that air could get through. What is the best way to insulate this space. Should I put some sort of vapor barrier up? Thanks for any help. :cool:

I would like to waterproof and insulate the basement of our new home and was wondering if my strategy would be effective and efficient. My main concern is waterproofing rather than insulating since it will only be an unheated work space. Because I'll be putting up either drywall or paneling, I'd like to side on overkill rather than chancing the possibility of having to make repairs later on. Our walls are poured concrete in sandy, porous soil. I would like to paint the walls with a waterproofing paint, insulate with kraft-faced fiberglass, and nail up either drywall or a cheap 4 X 8 paneling. The basement has already been studded and will allow for R-11 fiberglass. Do I need to use a plastic vapor barrier between the paneling and insulation if I use kraft-faced? Also, the plastic waste line will be behind the paneling, are there any precautions to take with it - besides access to the cleanout? Any other tips will be greatly appreciated. Thank you.
